This application claims the priority benefit of Taiwan application serial no. 109133337, filed on Sep. 25, 2020. The entirety of the above-mentioned patent application is hereby incorporated by reference herein and made a part of this specification.
BACKGROUND Technical FieldThe disclosure relates to a casing, particularly to a casing and a manufacturing method thereof.
Description of Related ArtThe casing is adapted as an exterior element of an electronic product, and the exterior element of the casing often comes in touch with its user's limbs, making the exterior surface of the casing easy to breed bacteria. With the rising awareness of health and hygiene, antibacterial treatment on the exterior surface of the casing has become a trend. As the user's limbs touch the exterior surface of the case frequently, the antibacterial protection on the exterior surface of the casing may be damaged or become invalid. Currently, there is no quick and intuitive determination mechanism for the user to determine the antibacterial protection on the exterior surface of the casing.
SUMMARYThe present disclosure provides a casing and a manufacturing method thereof, capable of assisting a user to determine the antibacterial protection of the casing in a quick and intuitive way.
The present disclosure provides a casing, including a substrate, a transparent fluorescent identification part, and a transparent antibacterial film. The transparent fluorescent identification part is disposed on the substrate. The transparent antibacterial film covers the substrate and the transparent fluorescent identification part.
The present disclosure also provides a manufacturing method for a casing, including the following steps. First, the substrate is provided. Then, a transparent fluorescent ink is printed on the substrate to form a transparent fluorescent identification part. Afterwards, a transparent antibacterial coating is applied on the transparent fluorescent identification part and the substrate to form a transparent antibacterial film, in which the transparent antibacterial film covers the substrate and the transparent fluorescent identification part.
Based on the above, the casing of the present disclosure adopts a quick and intuitive determination mechanism for the user to determine the antibacterial protection on the exterior surface of the casing. Furthermore, the user only needs to irradiate the exterior surface of the casing with ultraviolet light to observe the transparent fluorescent identification part, and determine whether the antibacterial protection on the exterior surface of the casing is still effective based on whether the transparent fluorescent identification part is damaged.
In order to make the above-mentioned features and advantages of the present disclosure more comprehensible, the following embodiments are described in detail in cooperation with the accompanying drawings.
Next, a paint is sprayed on the second surface 100b of the substrate 100 to form a paint layer 200, as shown in
Next, in
Next, in
Note that the substrate 100 is adapted as the main body of the casing, and the paint layer 200, the transparent film 300, the transparent fluorescent identification part 400, and the transparent antibacterial film 500 are sequentially formed on the substrate 100. That is to say, the substrate 100 is sequentially covered by the paint layer 200, the transparent film 300, the transparent fluorescent identification part 400, and the transparent antibacterial film 500, whereas the transparent antibacterial film 500 serves as the outermost layer of the casing, such that the outer surface of the transparent antibacterial film 500 which is exposed to the environment may be regarded as the exterior surface of the casing and has the antibacterial protection.
Please refer to
Furthermore, the casing 10 may be applied to various electronic products, such as a tablet computer, a smart phone, or a notebook. The transparent antibacterial film 500 serves as the outermost layer in the casing 10, so the outer surface of the transparent antibacterial film 500 exposed to the environment may be regarded as the exterior surface of the casing 10 and has the antibacterial protection. Once the user decides to determine the antibacterial protection of the transparent antibacterial film 500, the user only needs to irradiate the casing 10 with ultraviolet light and observe the transparent fluorescent identification part 400.
After the casing 10 is irradiated with ultraviolet light, the fluorescent identification part 400 reacts with the ultraviolet light, so that the user is able to observe the integrity of the transparent fluorescent pattern, the transparent fluorescent symbols, or the transparent fluorescent texts. Assuming that the observed transparent fluorescent patterns, transparent fluorescent symbols, and transparent fluorescent texts are worn out, it indicates that the transparent antibacterial film 500 has been worn out at a certain degree, arising doubts of insufficient antibacterial power. The above determination mechanism is fast and intuitive for the users.
Note that after irradiating the casing with ultraviolet light, if the user does not observe any transparent fluorescent patterns, transparent fluorescent symbols, and transparent fluorescent texts at all, it means that the casing may not have been treated with antibacterial treatment.
In summary, the casing of the present disclosure provides a quick and intuitive determination mechanism for the user to determine the antibacterial protection on the exterior surface of the casing. And the transparent fluorescent identification part disposed on the substrate may be presented in the form of transparent fluorescent patterns, transparent fluorescent symbols, and transparent fluorescent texts. In addition, the transparent antibacterial film acts the outermost layer of the casing, so the outer surface of the transparent antibacterial film exposed to the environment may be regarded as the exterior surface of the casing and has the antibacterial protection. Once the user decides to determine the antibacterial protection on the exterior surface of the casing, the user only needs to irradiate the exterior surface of the casing with ultraviolet light to observe the transparent fluorescent identification part, and determine whether the antibacterial protection on the exterior surface of the casing is still effective based on whether the transparent fluorescent patterns, transparent fluorescent symbols, and/or transparent fluorescent texts are damaged.
Although the present disclosure has been disclosed in the above embodiments, it is not intended to limit the present disclosure. Anyone with ordinary knowledge in the art can make some modifications and changes without departing from the spirit and scope of the present disclosure. Therefore, the scope of protection of the present disclosure shall be subject to those defined by the claims.
